Using augmented reality for accessing legacy transaction terminals

ABSTRACT

A method for accessing legacy devices via Augmented Reality (AR) devices. The method includes acquiring, via an AR device, an image of a keyboard of a legacy device. The method includes accessing customer commands for initiating of a transaction using the legacy device. The method includes determining a command sequence based, at least in part, on the customer commands, the command sequence mapping to a keystroke sequence to be entered using the keyboard. The method includes generating an overlay indicating a keystroke sequence corresponding to the command sequence. The method also includes displaying, via the AR device, the overlay by visually projecting the overlay over the keyboard of the legacy device.

BACKGROUND

Embodiments of the inventive subject matter generally relate to the field of augmented reality and, more particularly, to using augmented reality to access legacy transaction terminals.

Augmented Reality (AR) is a computer-generated environment that augments user's view of a real-world environment using computer-generated elements, such as sound, video, and/or other sensory outputs. AR can be implemented using computer-generated images that overlay a user-accessed view of a real-world. AR images can be displayed via AR glasses that are worn by the user, and thus can augment the real-world view seen by the user. For example, AR can be used to display supplemental images about certain elements in a field of vision of the AR glasses. The supplemental images are displayed in a way that aligns with real-world elements seen by the user.

A computer system that implements AR can access images of the real-world in the field of vision of the AR glasses. The computer system can then perform image analysis to detect certain elements in the accessed image. Based on element detection, the computer system can determine AR images to superimpose over the accessed image. The AR images can be moved and/or resized as the user moves the AR glasses and/or when the detected elements move, which can be caused by the user walking, user's head movement, movement of the detected elements, and/or via other movements. The user may also access a legacy transaction terminal, such as a legacy point-of-sale terminal. Such legacy transaction terminals typically are difficult to use for a novice user. The user may not obtain any benefit of using AR devices when accessing such a legacy transaction terminal.

DESCRIPTION OF EMBODIMENT(S)

The description that follows includes exemplary systems, methods, techniques, instruction sequences and computer program products that embody techniques of the present inventive subject matter. However, it is understood that the described embodiments may be practiced without these specific details. For instance, although many examples refer to AR, computer-generated images that simulate a user's physical presence in an imaginary environment can be used instead, such as Virtual Reality (VR). In some embodiments, AR and VR can be used interchangeably. In some embodiments, AR and VR can be used at the same time. In some embodiments, mixed reality (MR) can be used instead, where virtual and real worlds are combined. In MR, immersive environments are created that allow a user to interact with real world environments (such as via user-controlled robots) via real and virtual elements.

The AR device can determine objects and/or images at which the user is looking. The AR device can use eye-tracking, or another technique, to determine a field-of-view that is viewed by the user of the AR device (also referred to as a “user view”) of a real-world. For example, the AR device can have a camera (and/or other optical sensors) that can take videos and/or multiple photos, referred to collectively as image acquisition. The AR device can analyze the acquired images, such as by applying image analysis, to determine content of these images. For example, the AR device (or another device in communication with the AR device) can perform image analysis to detect certain elements in the viewed image(s). The AR device can also determine images and/or elements in these images that are most often viewed by the user. The AR device can also include one or more microphones for acquiring audio, or receive audio data from another device.

The AR device can be used to facilitate easy and efficient operator access with legacy devices. The AR device can acquire an image of a keyboard of a legacy device. For example, the AR device can acquire the image, from the user view, of the legacy device that is accessed by the user. The AR device can access customer commands for initiating of a transaction using the legacy device. For example, the AR device can access and analyze audio data to determine the customer commands. The AR device can determine a command sequence based, at least in part, on the customer commands. The command sequence can map to a keystroke sequence, which can be entered using the keyboard. The AR device can generate an overlay indicating a keystroke sequence that maps to the command sequence. The AR device can display, via an AR display, the overlay by visually projecting, in the user view, the overlay over the keyboard of the legacy device.

Therefore, the methods described herein allow the operator to use his or her AR device to access and use a legacy device, such as to quickly initiate processing of a transaction. The AR device can, based on audio data (such as customer data) acquired from a customer, determine a requested transaction. The AR device can then display an overlay over the keyboard of the legacy device for guiding the user how to access the keyboard of the legacy device. The following description, and associated Figures, illustrates various embodiments directed to the ideas listed above.

FIG. 1 is a system diagram illustrating embodiments of a system that uses an AR device for securely processing transactions that are initiated at another device. In an overview of a system diagram 100, a legacy device 102 includes a legacy display 106 and a legacy keyboard. An operator can use the legacy device 102 to initiate a transaction. The transaction can be for a purchase of a product and/or a service. The transaction can be composed of more elements, which need to be performed sequentially or in parallel.

The legacy device 102 can be a point-of-sale (PoS), a simple cash register, or another device that can be accessed by an operator for initiating and processing of a transaction. The legacy device 102 can include a legacy keyboard 104 having a plurality of physical keys, including physical keys 110 and 112. The operator can access the legacy device 102 via the legacy keyboard 104 to enter a keystroke sequence using the legacy keyboard 104 (e.g., by selecting the physical keys 110 and 112). The keystroke sequence can be entered by the operator, via the legacy keyboard 104 to perform operations corresponding to elements of the transaction. The legacy device 102 can display results of entering of the transaction elements via the legacy display 106. However, the operator can have difficulty with accurately selecting keys of the legacy keyboard 104 required to initiate each transaction.

The AR device 114 can provide easy access to the legacy device 102 for initiating of the transaction. The AR device 114 can process customer commands, and display, via an AR display 122, an overlay 126 that visually projects over the legacy keyboard 104. The overlay 126 can indicate what keys, and key selection order, of the legacy keyboard 104 to select for initiating of the transaction. Thus, the operator can, by accessing the keys of the legacy keyboard 104 via key indicators displayed by the overlay 126, easily operate the legacy device 102. In some implementations, the legacy keyboard 104 can be implemented using other input/output devices, such as a virtual keyboard that is displayed via the legacy display 106. In this embodiment, the AR device 114 would display the overlay 126 over the virtual keyboard.

The AR device 114 can be a device operable to generate an AR environment by augmenting a user's view of a real-world environment using computer-generated elements, such as by using sound, video, and/or other sensory outputs. The AR device 114 can be implemented using AR glasses or another device that generates images (or accesses generated images) and overlays a user-accessed view of a real-world. AR images can be displayed on an AR display 122 of the AR device 114. For example, the AR images can be displayed via AR glasses that are worn by the user (e.g., the operator of the legacy device 102), and thus can augment a real-world view seen by the user. The AR display 122 can overlay AR elements on the user view via the overlay 126. The AR elements can be visual elements generated by the AR device 114, or that are received from another device or server.

The AR device 114 can host an AR application 120 that acquires and/or processes various data, and based on the data processing, determines the AR elements to display on the AR display 122. The AR application 120 can be any type of an application that can access and analyze audio and video data that is acquired, for example, via the AR device 114. The AR application 120 can be a stand-alone application, or provide client functionality as accessed via a web browser. The AR device 114 can acquire an image of the legacy device 102, such as of the legacy keyboard 104. The AR application 120 can perform image analysis on the acquired images to determine whether the images include representations of certain elements. For example, the AR application 120 can determine a type of the legacy device 102 based on the image analysis of images of the legacy keyboard 104 and/or images of the entire legacy device 102.

The AR application 120 can communicate with a server 130 to determine the type of the legacy device 102. The communication can include certain characteristics of the legacy device 102, as determined by the AR application from the image analysis. The communication can include one or more of the acquired images (entire images or portions) of the legacy device 102. The server 130 can include a database of legacy devices, and determine, based on communication from the AR application 120, the legacy device type. The server 130 can then communicate the legacy device type to the AR application 120.

The AR application 120 can acquire audio data, which can be provided by a customer of the operator of the legacy device 102. The customer can be located in a close physical proximity of the operator (and thus of the AR device 114 worn by the operator). The AR application 120 can access an audio file with audio provided by the customer. The AR application 120 can analyze the audio data to determine whether the audio data includes customer commands for initiating of a transaction using the legacy device 102. The AR application 120 can analyze the customer commands to determine a command sequence that corresponds to elements of the transaction. The AR application 120 can analyze the command sequence to determine a keystroke sequence to be selected, by the operator, using the legacy keyboard 104 to initiate the transaction.

The AR application 120 can generate an overlay 126 indicating the keystroke sequence. The AR application 120 can display, via the AR display 122, the overlay 126 by visually projecting the overlay 126 over the legacy keyboard 104. In some embodiments, the overlay 126 can substantially line up, in the user view, with the legacy keyboard 104, such that key indicators 118 and 119 visually line up with the corresponding physical keys 110 and 112, respectively. In some embodiments, the AR application 120 can also determine a keystroke sequence order that indicates an order in which the physical keys of the legacy keyboard should be selected by the operator. The overlay 126 can visually indicate the order in which the physical keys should be accessed, such as by first projecting the key indicator 118 over the physical key 110, without projecting the key indicator 119 over the physical key 112. Once the AR application 120 detects a user selection of the key 110, the AR application 120 can cease displaying the key indicator 118 over the physical key 110, and instead display the key indicator 119 over the physical key 112.

In some embodiments, AR application 120 can receive a user selection 108 by tracking user gestures. For example, the AR device 114 can use cameras to track location and movement of user's arm, hand, and/or fingers to determine whether the operator selects a physical key that is indicated by one of the key indicators 118 or 119. If the overlay 126 is properly aligned with the legacy keyboard 104, the user selection 108 of the key indicator 118 also selects the physical key 110 (that is mapped to the key indicator 118). The AR device 114 can determine the user selection 108 based on user's gestures as determined by the cameras. In some embodiments, the AR device 114 can use motion detection sensors such as infrared sensors and/or photodetectors to detect hand motions and/or gestures. The AR device 114 can track the movement of user's hand via tracking gloves worn by the user, where the tracking gloves can include sensors that detect user's hand and/or finger movements. In some embodiments, the AR device 114 can determine the user selection 108 based on position and/or signals received from a pointing device held by the operator.

In some embodiments, the AR application 120 can generate a shortcut key (as discussed below with reference to FIG. 4). For example, the AR application 120 can use the key indicator 119 as the shortcut key instead of the key indicator 119 being mapped to the physical key 112. The AR application 120 can determine to place a location of the key indicator 119 on the overlay 126 so it maps to another physical key of the legacy keyboard 104. The AR application 120 can determine to place the location of the key indicator 119 on the AR display 122 such that it does not map to any physical keys of the legacy keyboard, and is only accessible via the AR display 122, i.e., as a virtual key. Upon detection of selection of the virtual key by the user selection 108, the AR device 114 can provide haptic feedback to the user to indicate that the user selection 108 has been received.

The AR device 114 can communicate at least a portion of the command sequence to the legacy device 102 via a legacy communication link 124. The legacy communication link 124 can be implemented using a serial RS-232 interface, a general purpose interface (GPIB or HPIB), a parallel port interface, or any one of legacy serial or parallel interfaces for enabling communication (e.g., data transfer) between devices such as an IEEE 1394, parallel SCSI, mini-DIN, among others. The legacy communication link 124 can be implemented using legacy wireless communication technology such as RF data links or UHF or VHF data links. In some implementations, the legacy communication link 124 can be implemented using a newer communication interface such as Universal Serial Bus (USB).

FIG. 2 is a flow diagram illustrating embodiments of operations for using an AR device to access legacy transaction terminals. The method of FIG. 2 is described with reference to the systems and components described in FIG. 1 (for illustration purposes and not as a limitation). The example operations can be carried out by the AR application 120.

Beginning with 202, the AR application acquires an image of a keyboard of a legacy device. With reference to FIG. 1, the AR application 120 can acquire an image of the legacy keyboard 104 that is being used by the operator. The AR application 120 can determine, based on image analysis of the image, a device type of the legacy device 102. The AR application 120 can access, based on the device type, a keyboard layout of the keyboard from a database of keyboard layouts. In some embodiments, the AR application 120 can locally (i.e., local to the AR device 114) determine the device type. The AR application 120 may also locally determine the keyboard layout based on the device type, or communicate the device type to the server 130 for determination of the keyboard layout. In some embodiments, the AR application 120 can communicate the image or the results of the image analysis to the server 130 for determination of the device type. The server 130 would then communicate the device type and the keyboard layout to the AR device 114.

At 204, the AR application accesses customer commands for initiating a transaction using the legacy device. With reference to FIG. 1, the AR application 120 can acquire and access (or access previously acquired) audio data, which can be received from a customer that is interfacing with the operator of the legacy device 102. The AR application 120 can perform voice analysis on the audio data to determine customer commands. The AR application 120 can perform the voice analysis locally, or can communicate with the server 130 for sending the audio data and receiving results (i.e., customer commands) of the voice analysis. It is noted that the customer commands can be generated based other means of communication beside voice. For example, the AR application 120 can acquire, via the camera(s), a video of sign language provided by the customer. The AR application 120 can determine the customer commands based on analysis of the sign language video. In some embodiments, the AR application 120 can use the camera(s) to acquire visual cues from body movements, gestures, and other non-verbal communication from the customer. The AR application 120 can also use the customer visual cues when determining the customer commands.

At 206, the AR application determines whether the AR device is in a training mode. With reference to FIG. 1, the AR application 120 can determine that the AR device 114 is being used to train based on the legacy device 102. The training mode can also be for training elements (e.g., transaction rules and/or databases) of the server 130. If the AR application determines that the AR device is in the training mode, flow continues at 208. Otherwise, flow continues at 210.

At 208, the AR application performs training for the legacy device. The AR application 120 can thus be placed in a training mode, where the AR application 120 acquires and analyzes images, or transmits the images to the server 130, of the operator selecting various keystrokes along with associated customer commands (such as received at 204). In some embodiments, the AR application 120 can acquire, via the AR device 114, a set of images corresponding to a training set of keystrokes for the transaction using the legacy device 102. In some embodiments, the AR application 120 can locally correlate the training set of keystrokes to the set of customer commands to generate a set of command sequences. Using the set of command sequences and the training set of transactions, the AR application 120 can generate a set of transaction rules for the legacy device (and optionally for a type of a merchant for which the transaction is initiated). In some embodiments, the AR application 120 can transmit the image and audio data to the server 130, so the server 130 can perform the correlation, generate the set of command sequences, and/or generate the transaction rules for the legacy device 102.

At 208, in some embodiments, 208 the AR application 120 can determine possible shortcut sequences. For example, the AR application 120 can determine a portion of the command sequence or the subset of the keystroke sequence for the shortcut key. Based on the training set of transactions, the AR application 120 can determine several shortcut keys for use at 214. The AR application 120 can display, via the overlay 126, several portions of the command sequence or subsets of the keystroke sequence corresponding to training set of transactions. The AR application 120 can receive user input indicating whether certain portions of the command sequence (or corresponding subsets of the keystroke sequence) are accurate.

At 210, the AR application determines a command sequence based on the customer commands. The command sequence maps to a keystroke sequence for the legacy keyboard 104. In some embodiments, the AR application 120 can access a command list for the legacy device 102 based on the device type. The AR application 120 generates, based on the device type, the keystroke sequence that corresponds to the command sequence. In some embodiments, the AR application 120 and/or the server 130 use transaction rules (e.g., associated with the legacy device) when determining the command sequence.

In some embodiments, the AR application 120 can determine whether steps of the customer commands are in order acceptable by the legacy device 102. The AR application 120 can, in response to determination that the steps are not in order acceptable by the legacy device 102, re-organize order of the steps of the customer commands. The AR application 120 can determine the command sequence that corresponds to the customer commands in the re-organized order.

In some embodiments, the AR application 120 can acquire, via the AR device 114, an image of the customer that provides the customer commands for the transaction. The AR application 120 can access (locally and/or via the server 130) customer preferences for the customer, wherein the customer preferences modify at least one of the customer commands. The AR application 120 can determine the command sequence further based on the customer preferences.

At 212, the AR application determines whether to generate a shortcut key. The AR application 120 can determine to generate the shortcut key based, for example, on complexity of the transaction. If the transaction is determined to be complex (e.g., above a certain complexity level threshold), then the AR application 120 can determine to generate the shortcut key. The complexity level threshold can be adjusted based on determination of a competency level of the operator, e.g., the lower the operator competency, the lower the complexity level threshold. The determination of whether to generate the shortcut key can be based on whether the AR device 114 can communicate over a communication link (such as the legacy communication link 124) with the legacy device 102.

At 212, the AR application 120 can also determine what type of the shortcut key to generate. The AR application 120 can generate the shortcut key as a virtual key, i.e., that a key indicator visible via the AR display 122 but which does not map to a physical key on the legacy keyboard 104. The AR application 120 can also map the shortcut key to a key on the legacy keyboard 104, e.g., via a key indicator on the overlay 126. The shortcut key type determination can be made based on whether the legacy keyboard 104 and the legacy device 102 can support use of a physical key without directly affecting the transaction (i.e., the selection of the particular physical key would not affect the transaction until communication is received by the legacy device 102 via the legacy communication link 124). If the AR application determines that to generate the shortcut key, flow continues at 214. Otherwise, flow continues at 216.

At 214, the AR application generates the shortcut key. The shortcut key can map to at least a portion of the command sequence (that maps to a subset of the keystroke sequence). Upon detection of the user selection of the shortcut key (i.e., from the AR display 122), the AR application 120 can communicate the at least a portion of the command sequence (or the subset of the keystroke sequence) associated with the shortcut key to the legacy device 102, such as via the legacy communication link 124. The AR application 120 can use, for the shortcut key, the portion of the command sequence or the subset of the keystroke sequence as determined at 208.

At 216, the AR application 120 generates the overlay indicating the keystroke sequence mapping to the command sequence. If the shortcut key is generated at 214, the overlay 126 can also include the key indicator for the shortcut key. The AR application 120 can determine the operator of the AR device 114. The AR application 120 can access operator preferences for the operator, where the operator preferences can indicate how to modify at least one element of the overlay. The operator preferences can indicate to modify how a certain key indicator is displayed and/or how long each key indicator is displayed after the operator selects the certain key indicator. For example, the operator preferences can indicate that the first key indicator is colored green, and the second key indicator is colored red.

At 218, the AR application 120 displays, via the AR device, the overlay over the keyboard of the legacy device. The AR application 120 can display the overlay 126 to substantially line up with the legacy keyboard 104, in the operator's user view, via the AR display 122. The overlay 126 substantially lines up when the key indicators 118 and 119 visually overlap, in the user view, the physical keys 110 and 112 of the legacy keyboard 104, respectively. The key indicators 118 and 119 can be displayed in the keystroke sequence order, so the transaction is accurately prompted, to the operator, for selection via the legacy keyboard 104.

At 220, the AR application monitors entered keystrokes and generates new overlays based on errors. For example, once the AR application 120 detects a user selection of the physical key 110, the AR application can cease displaying the key indicator 118 over the physical key 110, and instead display the key indicator 119 over the physical key 112. If the key indicator 119 (and thus the physical key 112) is not selected by the user, and another physical key is instead selected, then the AR application 120 can determine that an error occurred.

The AR application 120 can determine a sequence of user keystrokes that are entered by the operator. The AR application 120 can compare the sequence of user keystrokes to the keystroke sequence. The AR application 120 can determine, based on the sequence comparison, an error in the sequence of user keystrokes. The AR application 120 can determine, based on the error and the keystroke sequence, a new keystroke sequence. The AR application 120 can then generate a new overlay indicating the new keystroke sequence.

FIG. 3 illustrates examples of customer commands, and example corresponding command sequence and keystroke sequence, as used by the AR application of FIGS. 1 and/or 2. Element 302 illustrates an example of voice data (corresponding to audio data) that can be accessed by the AR application 120. The AR application 120 can (locally and/or by communicating with the server 130) perform voice analysis on the voice data 302 to determine customer commands 304-312. The AR application 120 can (locally and/or by communicating with the server 130) determine a command sequence 320 based on the on the customer commands 304-312. The AR application 120 can (locally and/or by communicating with the server 130) determine a keystroke sequence 330 based on the on the command sequence 320. The AR application 120 can (locally and/or by communicating with the server 130) determine a shortcut keystroke subset 350 of the keystroke sequence 330. The shortcut keystroke subset 350 can be used for generation of the shortcut key.

The AR application 120 can analyze the customer commands 304-312 and determine that the customer command 304 indicates customer intent, but is not translatable into an element of the command sequence 320. Based on the customer command analysis, the AR application 120 can determine that the customer commands 306-310 translate into respective elements 322-326 of the command sequence 320 associated with a portion of the transaction (e.g., the actual order for the customer). Based on the customer command analysis, the AR application 120 can determine that the customer command 312 translates into element 328 of the command sequence 320 that indicates a type of the transaction (e.g., that the transaction is a to-go order).

The AR application 120 can then analyze the elements 322-328 of the command sequence 320 and determine the keystroke sequence 330. This keystroke sequence determination can be based on the transaction rules and type of the legacy device, as each legacy device can have a different keystroke sequence and/or a different legacy keyboard. The transaction rules can be different for different merchant locations even if the same legacy device is used. For example, the legacy device at a merchant A may have a different set of transaction rules from the same legacy device at a merchant B. Based on the command sequence analysis, the AR application 120 can determine that element 322 of the command sequence 320 maps to keystrokes 334-336. Similarly, the AR application 120 can determine that elements 324, 326, and 328 of the command sequence 320 maps to keystrokes 338-340, 342, and 344, respectively. The AR application can determine, based on the legacy device type and/or the transaction rules, that keystrokes 332 and 346 are necessary to initiate and terminate entering of the transaction, respectively.

The AR application 120 can also generate a shortcut key based on a at least a portion of the command sequence 320. The AR application 120 can determine the shortcut command subset 350 that corresponds to the keystrokes 334-344 (for the command sequence 322-328), but would still require the operator to use keystrokes 332 and 346 for initiating and terminating entering of the transaction.

FIGS. 4A and 4B are diagrams illustrating embodiments of a display shown by an AR device for accessing legacy transaction terminals. FIG. 4A illustrates the AR display 122 as seen by the operator 402 via the AR device 114. The user can see a user view 306 via the AR display 122. The user can see the overlay 126, displayed via the AR display 122, that overlaps with the legacy keyboard 104. The overlay 126 can include key indicators 118, 119, 416, and 418. Each of the key indicators 118, 119, 416, and 418 can map to a separate physical key on the legacy keyboard 104. The AR application 120 can display one key indicator at a time for the key indicators 118, 119, 416, and 418, in order as indicated by the keystroke sequence 330.

The AR display 122 can also display a shortcut key 420. The AR application 120 can associate user selection of the shortcut key with the commands of the shortcut command subset 350. In FIG. 4A, the AR application 120 displays the shortcut key 420 outside of the overlay 126, and thus the shortcut key is not mapped to any keys of the legacy keyboard 104.

FIG. 4B illustrates how the overlay 126 is displayed with relation to the legacy keyboard 104. The overlay 126 can include key indicators 118, 119, 416, and 418, that map to physical keys 110, 112, 412, and 414, respectively. The AR application 120 can display, via the overlay 126, the key indicators in the order indicated by the keystroke sequence 330, i.e., in the keystroke sequence order. For example, the AR application 120 can only display the first key indicator 118 of the keystroke sequence 330, while the remaining key indicators 119, 416, 418, and 420 are not made visible on the overlay 126. Once the AR application 120 detects the user selection of the physical key 110 that is mapped to by the key indicator 119, the AR application 120 can display the second key indicator 119 of the keystroke sequence 330, while not displaying the first key indicator 118 or the remaining key indicators 416 and 418. The AR application 120 can display each key indicator by only displaying the next key indicator as indicated by the keystroke sequence order, by visually highlighting the next key indicator, and/or by visually dimming the remaining (i.e., not the next key indicator), among other techniques.

In some embodiments, the AR application 120 can also display a virtual display 415 with one or more elements. The virtual display 415 can map to the legacy display 106, or can map to another area of the AR display 122. The virtual display 415 can display additional information about the transaction and/or the customer. The virtual display 415 can display portions of the customer commands 304-312, the command sequence 320, and/or the current and/or the next keystroke of the keystroke sequence 330. The virtual display 415 can display prompts for the operator to clarify any ambiguous customer commands.

The AR application 120 can detect the user selection 108, which can indicate a selection, by the user 402, of one of the physical keys 110, 112, 412, and 414. The AR device 114 can detect the user selection 108 of the physical key via a variety of methods, including by tracking user's 402 gestures, detecting hand motion of the user 402, and/or receiving signals from a pointing device held by the user 402. The AR application 120 can determine whether the detected keypress is for the same physical key as indicated by the overlay 126 (i.e., for a next step of the keystroke sequence). If the AR application 120 determines that the user selection 108 is for a different physical key, the AR application 120 may determine that an error occurred, and can determine a new keystroke sequence and/or a new overlay to complete the transaction.

The shortcut key 420 can be displayed inside of the overlay 126, and can be mapped to another physical key of the legacy keyboard 104. The AR application 120 can map the shortcut key 420 to the command subset 350 that maps to the keystrokes 334-344 (for the command sequence 322-328). For example, the keystroke 332 can be mapped to the physical key 110 (which is indicated by the key indicator 118). If the AR application 120 does not use the shortcut key, the AR application 120 can select the next key indicator to display from the keystroke sequence order. If the AR application 120 uses the shortcut key 420, the AR application 120 can display the shortcut key 420 once the AR application 120 detects the user selection of the physical key 110 as mapped by the key indicator 119. Upon detection of the user selection of the shortcut key 420, the AR application 120 can communicate the portion of the command sequence (and/or the corresponding keystrokes) over the legacy communication link to the legacy device 102. The AR application 120 then can display the next key indicator 418 (as indicated by the keystroke sequence order).

FIG. 5 is a timing diagram illustrating operations for using AR for secure transactions, according to some embodiments. As shown by FIG. 5, the AR application 120 communicates with the server 130. The AR application 120 can also communicate with the legacy device 102. The communications of FIG. 5 can be performed over one or more communication networks. Portions of the timing diagram of FIG. 5 correspond to the flow diagram of FIG. 2.

At 502, the AR application 120 acquires, via the AR device, an image of a keyboard of the legacy device. At 504, the AR application 120 accesses customer commands for initiating a transaction using the legacy device. At 506, the AR application 120 can determine whether the training mode is being used. At 508, if the AR application 120 determines that the training mode is not being used, the AR application 120 can communicate with the server 130, where the communication can include the customer commands and/or the image. At 510, the server 130 can determine the command sequence based on the customer commands, the image, and/or associated transaction rules. At 510, the server 130 can determine a type of the legacy device based on the image. At 512, the server 130 can communicate the command sequence and/or the type of the legacy device, including a layout of the legacy keyboard, to the AR application 120.

At 514, the AR application 120 can determine the command sequence based on the communication received from the server 130. At 516, the AR application 120 can determine whether to generate a shortcut key, and generate the shortcut key accordingly. At 518, the AR application 120 generates the overlay and displays the overlay over the legacy keyboard. At 520, the legacy device 102 can receive a user selection for a physical key. At 522, the AR application 120 can determine whether the physical key selected by the operator matches the currently displayed key indicator of the keystroke sequence order. At 524, if the AR application 120 determines that the user selects the shortcut key, the AR application 120 can communicate the subset of the command sequence to the legacy device. At 526, the legacy device 102 can implement the subset of the command sequence. At 528, the legacy device 102 can communicate (e.g., via the legacy communication link) result of the subset of the command sequence to the AR application 120.
